3 3 Battery Disconnect Switches

4 4 Battery Control Center (Cont) Battery Disconnect Switches Each switch controls a magnetically latched relay with power applied to coil only momentarily to latch the switch Unlatch by applying current in the other direction If chassis or coach battery is disconnected, it is automatically connected if ignition is switched on A lockout feature prevents disconnecting the chassis battery when the ignition switch is on

5 5 Battery Control Center (Cont) What does NOT work with Coach battery disconnected: 12v Lighting / 12v Power Outlets Water Pump / Dash Radio / Bedroom Radio Furnace / Refrigerator / Water Heater Air Conditioners Generator

6 6 Battery Control Center (Cont) What does NOT work when Chassis battery disconnected with ignition switch OFF: Steps Clearance lights Fog lights Slides Leveling Jacks Turning On the ignition switch automatically causes both battery disconnect relays to change to the connected position The chassis battery cannot be disconnected using the disconnect switch with ignition ON The coach battery can be disconnected using the disconnect switch.

7 7 Battery Control Center (Cont) What does NOT work when both Chassis battery and Coach battery are disconnected: Propane detector Propane automatic shutoff valve closes to prevent any propane use while the detector has no power

8 8 Battery Control Center (Cont) Charging and Auxiliary Starting Relay Located on back wall in electrical bay Charging Automatically connects chassis and coach batteries in parallel to allow charging of both when: Either battery voltage reaches 13.2 Relay automatically isolates batteries from each other when voltage drops to: 12.6 with ignition off 12.2 with ignition switch on. Auxiliary Starting Dash switch used to connect chassis and coach batteries in parallel while switch is held ON Start engine with dead chassis battery Start generator with dead coach battery
